Why are transformers so afraid of rust?

Transformers are not indestructible. Rust in the core and windings—their lifeblood—can lead to increased iron losses, poor heat dissipation from the windings, decreased efficiency, and a hidden increase in power consumption. In severe cases, it can cause localized overheating, posing a safety hazard. Rust in fasteners and structural components can cause bolts to seize and reduce the strength of the enclosure, complicating routine maintenance and troubleshooting, significantly increasing operational costs and time.

Corrosion is a slow, irreversible chemical reaction, accelerated dramatically by challenges such as salt spray in coastal areas, polluted gases in industrial areas, and high humidity during transportation and storage. For transformers, rust prevention is no small matter; it is crucial for ensuring power grid safety and improving economic efficiency. The Evolution and Breakthroughs of Rust Prevention Technology
Humanity's battle against rust is a long one, and methods are constantly evolving. Traditional methods, such as applying rust-preventive oil or butter, are cumbersome, easily contaminated by dust, and require thorough cleaning before use, otherwise the transformer oil quality will be affected. Their protection period is short, making them inadequate for long-term storage and harsh transportation environments.

The advent of VCI (vapor corrosion inhibitor) technology is revolutionary. This technology eliminates the need for direct metal contact. In a confined space, the anti-rust ingredients continuously evaporate and adsorb onto the metal surface, forming a protective film just a few molecules thick that effectively blocks moisture and corrosive substances. Even within complex internal structures, crevices, and holes, this technology provides comprehensive, no-blinds protection, lasting for years. Core Requirements of Modern Anti-Rust Materials
An excellent modern anti-rust packaging material should be a systematic solution, demonstrating the following capabilities: High Efficiency and Long-Lasting: Provides continuous protection for years, adapting to harsh environments such as temperature and humidity fluctuations.
Full Coverage: Protects every geometric surface of the product, including hard-to-reach crevices and delicate areas.
Clean and Environmentally Friendly: The material itself leaves no residue or contamination, allowing it to be used directly after removing the packaging.
Convenient and Intelligent: Simple operation, eliminating the need for complex painting and cleaning processes.
Customizable: Provides personalized solutions based on the size, shape, and specific needs of the equipment.

Choosing an advanced rust prevention solution isn't just a cost expense; it's a crucial investment. It's an investment in the stability of the equipment's value, absolute operational reliability, reduced maintenance costs, and ultimately, the long-term security of the entire power grid system.

With continuous advancements in materials science and technology, rust prevention technology is evolving towards a more environmentally friendly, intelligent, and integrated approach. In the future, we may see "smart rust prevention films" integrated with the Internet of Things (IoT) that monitor temperature, humidity, and corrosion factors inside packaging in real time, enabling predictive maintenance.
